FIG-6 United States Patent 41/ 67,111 US. Cl. 24265 2 Claims Int. Cl. A44b 11 /22; A44c /18 ABSTRACT OF THE DISCLOSURE A band provided with a buckle for loose and tight fastening, said band being capable of being fastened by (l) inserting check pieces provided, facing opposite to each other, along the edges at both sides of an openable plate fitted openably to said buckle into grooves provided in the edges at both sides of said band so that said check pieces can slide along said grooves, (2) setting a supporting plate formed by bending an end of said openable plate into depressions of the base plate of said buckle and (3) thrusting a click at the top of a spring plate fitted to said base plate into one of said tightening grooves of said band through the small hole provided in said openable plate.

Background of the invention This invention relates to a band with a buckle used as a wrist watch bracelets or a waist belt.

There have been conventional types of waist belts with buckles capable of freely loosening and fastening the bands at an optional place. These belts are so designed as to be fastened and made stationary at an optional place by bending both edges of the buckles in a U shape, in serting the bands into these bent parts and pressing the reverse side of the belts with the protruding part of a fastening piece loosely fitted to an end of the buckles. These buckles, however, have the defect that in proportion as said protruding part of the fastening piece is worn out, the fastening tends to become loosish, thus making it impossible to obtain perfect fastening. Again in the case of wrist watch bracelets, there have been various conventional types of bands such as those fastened by preparing holes in the bands themselves and simply inserting the check bar of the clasps into one of said holes (this system has long been in use also in the case of waist belts), and those fastened by the expansibility of the bands themseleves. However, the former cannot be made stationary at other optional places Where there are no such holes prepared, and the latter gradually lose said expansibility and easily become unusable.

Summary of the invention This invention eliminates the defects of such conventional types of bands. A band of this invention has a pair of check pieces facing opposite to each other and shaped like U by bending the edges at both sides of an openable plate loosely fitted to the base plate of the buckle and the edges of said check pieces are inserted into grooves provided in the edges at both sides of said belt so that said edges of the check pieces may freely slide along said grooves in the longitudinal direction. When said openable plate is shut, a supporting plate formed by bending an end of said openable plate engages with supporting pieces provided to said base plate of the buckle, and at the same time a click at the top of a spring plate provided to said base plate of the buckle is thrust into a groove of the joint of said band or into a fastening hole of said band after passing through the hole made in the lid of said base plate and also the hole made in said openable plate,

Description of preferred embodiments FIG. 1 shows a waist belt and FIG. 2 shows a wrist watch bracelet. The main bodies of these two bands consist of buckles 1 and belts 2. Said buckle 1 is provided with the connecting pieces 4 and 5 protruding on the edges at both sides near the end of the base plate 3 for connecting the belt 2, and with the side plates 6 and 7 standing along both sides of said base plate 3, the ends of said side plates 6 and 7 which extend in the direction of said connecting pieces 4 and 5 being bent toward the inside to form the depressions 8 and 9 in the side thus formed, and these parts acting as the supporting pieces 10 and 11 which, together with said side plates 6 and 7, form the supporting part 12 of said base plate 3.

At the other ends of the side plates 6 and 7 there is provided the shaft 13, on which the base 16 of the spring plate 15 is loosely fitted with the click 14 facing upward, said spring plate 15 being slightly bent in arc shape and the top thereof forming said click 14. The spring plate 15 is provided in the interior of the box formed by the supporting part 12 and the lid 17 covering it, said lid 17 having the hole 18 out of which the click 14 of the spring plate 15 is sticking. The base 26 of said lid 17 is loosely fitted on the shaft 13 so as to make the lid 17 openable.

The shaft 13 loosely fixes the base 20 of the openable plate 19. Said openable plate 19 is provided with the U-shaped check pieces 21 and 22 along the edges at both sides of its back, said check pieces 21 and 22 facing opposite to each other as integral parts of said openable plate 19 and serving as the sliding surface 30. The front edge of the openable plate 19 is bent to form the supporting plate 24 provided with a protruding strip 23 on its inside. Near said supporting plate 24, the openable plate 19 has the hole 25 which is loosely passed through by the click 14. This openable plate 19 is so designed as to be able to rise and fall (i.e., open and close) with the shaft 13 as the fulcrum and when the openable plate 19 is closed it covers the surface of the supporting part 12 so that the protruding strip 23 of the supporting plate 24 of said openable plate 19 may engage with the depressions 8 and 9 of the supporting pieces 10 and 11 of the supporting part 12 to support said openable plate 19 with said supporting part 12. At that time the tip of the click 14 of the spring plate 15 is pushed out of the hole 25 prepared in the openable plate 19 toward the sliding surface 30.

An end of the band 2 is fastened to the connecting pieces 4 and 5 of the buckle of the above-mentioned construction as shown in FIG. 1 0r FIG. 2 and connected with the shaft 41. The belt may be provided with the grooves 27 and 28 in the edges at both sides thereof in the longitudinal direction for increasing the effect of the function of this buckle, and therefore it is advisable to provide such grooves as occasion demands. Also the band 2 may be provided with the fastening holes 29 along the center on the inside thereof as shown in FIG. 1 or with the grooves 31 and 32 along the edges at both sides thereof as shown in FIG. 2 for obtaining the same effect. However, since the band 2 shown in FIG. 2 is composed of each of the connecting pieces 33, it is not particularly necessary to provide said fastening holes 29 as shown in FIG. 1, if the clearances between said multitude of connecting pieces 33 are utilized as the fastening grooves 34. Incidentally, the FIGS. 1 and 2 show that the fixing part 38 of the band 2 is fixed to the connecting pieces 4 and 5. In FIG. 2, 35 are the fixing parts of the watch, 36 is the inserting part at an end of the band, and 37 is the loop for fastening said inserting part 36, respectively.

FIG. 6 shows the longitudinal section of the band body with the band 2 composed of the multitude of connecting pieces 33 explained in FIG. 2 fixed to the buckle 1, and, as is seen also from FIG. 2, if the inserting part 36 is inserted into the recess formed by the U-shaped check pieces 21 and 22 of the openable plate 19 of the buckle 1, the band 2 is able to slide in said recess as the surface at this part of the openable plate 19 is the sliding surface 30. In case the inside of said check pieces 21 and 22 is larger than the thickness of the band 2, the grip is weak and the band 2 becomes shaky in the recess. Therefore, in order to achieve a smooth and stable sliding of the band 2 on the surface of the openable plate 19 with only slight clearances between said inside of the check pieces 21 and 22 and said thickness of the band 2 by almost equalizing them both, the ends 39 and 40 of the check pieces 21 and 22 are so designed that they can loosely fit in the grooves 27 and 28 provided in the edges at both sides of the band 2.

As seen from FIGS. 2 and 3, when the openable plate 19 in open, the band 2 may be freely moved since there is no obstacle there, but when the openable plate 19 is closed and the protruding strip 23 of the supporting plate 24 is pushed into the depressions 8 and 9 of the supporting pieces 10 and 11 which are the integral parts of the base plate 3 with the band 2 inserted under the openable plate 19, the openable plate 19 comes in tight contact with the base plate 3. At that time the click 14 coming out of the hole 18 of the lid 17 is pushed out of the hole 25 of the openable plate 19 toward the back (i.e., the sliding surface) thereof. If the band 2 is pulled, said band slides forward (i.e., in the direction of the arrow shown in FIG. 6) eliminating the elasticity of the spring plate 15, but does not slide backward (i.e., in the opposite direction) since the click 14 is caught into one of the fastening holes 29 or fastening grooves 34. In other words, because the spring plate is bent forward in arc shape, if the band 2 is pushed forward in the direction of the arrow or if the inserting part 36 is pulled, the multitude of connecting pieces 33 comprising the rear side or the Whole of the band 2 push in the click 14 of the spring plate 15 against the elasticity of said spring plate 15 which otherwise comes out of the holes of the openable plate 19 and is constantly repelling upward, and slide in this state. On the other hand, if the band 2 is pulled backward in the opposite direction, the click 14, by its own elasticity, comes into one of the fastening holes 29 or fastening grooves 34 formed by the clearances between the connecting pieces of the band 2, and the spring plate 15, in the rising state, comes against the wall of the hole 25 of the openable plate 19 to make the band 2 immovable. So the belt is surely fastened at any optional position. While the belt is in service the openable plate 19 is kept closed like this and the extruding strip 23 of the supporting plate 24 is kept engaging with the depressions 8 and 9 of the supporting pieces 10 and 11, thus completely eliminating the fear for getting loose. To unfasten the band 2 from the buckle 1, pull the band by holding the tip or the inserting part thereof, and the supporting plate 24 of the openable plate 19 will come off the supporting pieces 10 and 11 of the supporting part 12 to allow the openable plate 19 to rise, so that the click 14 may also come off the band, thus regaining the free move of the band 2.

As explained above, a band of this invention is not only easy to remove and adjust the fastening, but also is free from the fear for being caught in by other objects or becoming obstructive to the wearer as the buckle 1 is hidden behind the band 2 when the belt or bracelet is worn round the waist or wrist. Furthermore, the band is smart to look at because the buckle 1 itself is hardly noticeable from outside.
